Is Mobility a Curse?

Providing you with useful information on smartphones and PDAs isn't my only online commitment. I write for a freelance blog, and am a partner in a local blog network. So I'm glad that I've got a free Wi-Fi account, and failing that, I rely on the more expensive (and admittedly less reliable) cellular web access.
But somehow, I think these mobile tools make me feel less obliged to work. If perhaps I was forced to work on a desktop, maybe I'd plan better, maximizing the times I have access to the Internet. Since I can practically work anywhere, I don't feel the urgency required to get the job done immediately.
In other words, I can afford to dilly-dally. Unfortunately, when I somehow can't access the net (my home ISP is notoriously unreliable, and an earthquake recently cut off my country's main internet backbone), I have to scramble and cram to fulfill my commitments. I end up producing output that definitely isn't my best.
I realized that mobility is not a curse, but a privilege. Something I should be grateful for, not to take for granted. Once again, the effectivity of a tool depends on its user. That's why I'm writing this post now, during a short break, instead of being a lazy bum and putting it off for later.
